.' STRAINER.

Specification of Letters Patent.

Patented Nov. 12, 1918.

Application filed June 28, 1917. Serial No. 177,556.

To all whom it may concern:

Be it known that I, DAVID M. BYLANDER, a citizen of the United States,residing at Lake Wilson, in the county of Murray and State of Minnesota,have invented certain new and useful Improvements in Strainers, of whichthe following is a specification.

This invention relates to new and useful improvements in strainers andthe principal object of the invention is to provide a device of thisnature with a plurality of straining mediums through which the liquid tobe strained must pass.

Another object of the invention is to make each medium detachable so thesame may be cleaned or renewed.

A further object of the invention is to make the mediums of graduallyincreasing fineness of mesh, beginning at the top to better strain thefluid.

Another object of the invention is to provide a device of thischaracter, which is simple and durable in construction, reliable andefiicient in operation and one which can be manufactured and placed uponthe market at a minimum cost.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings, wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a central sectional view through one form of the invention.

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 is a section on line 33 of Fig. 1.

Fig. 4 is a section on line 4-4 of Fig. 1.

Fig. 5 is a view of a modification, parts being shown in section.

In these figures 1 represents a straining funnel of the usual type, andthis funnel at its outlet end is provided with a cylindrical screwthreaded part 2. 3 indicates a straining medium located at the beginningof said cylindrical portion, this medium being formed of wire gauze orthe like. 4 inclicates a screw threaded ring having a straining medium 5located centrally thereof and the upper part of this ring is adapted tobe screwed into the cylindrical part 2. 6 represents another ringprovided with the straining medium 7 having its upper part screwthreaded and adapted to be screwed into the ring 4. By joining therings, and the rings of the body part of the funnel in this manner, thespout of the funnel will taper as in its usual form and may be insertedinto openings of various sizes. As more clearly shown in Figs. 2, 3, and4, the rings consecutively decrease in diameter, the lower ring beingthe smallest. The lower part of the ring 6 is left plain as at 8. Themedium 3 is of coarse mesh, the medium 5 is of finer mesh, while themedium 7 is of still finer mesh, thus the fluid must pass through thethree mediums of gradually increasing fineness of mesh so that it willbe thoroughly strained and the impurities removed therefrom.

In the modification shown in Fig. 5 I show a pail 9 provided with aspout 10 whichis provided with my improved form of strainer.

It will be seen that the rings with the straining material therein maybe easily separated for cleaning purposes or when it is desired to useonly the one medium.

After using the device it may be separated and the different partscleaned and the parts placed together again in the minimum amount oftime.

It is thought from the foregoing that the advantages and novel featuresof my invention will be readily apparent.

I desire it to be understood that I may make. slight changes in theconstruction and in the combination and arrangement of the severalparts, provided that such changes fall within the scope of the appendedclaim.

I claim as my invention:

A strainer comprising a body part having an internal screw threadedoutlet, a ring having screw threaded ends, said ring being engaged atone end by said threaded outlet, :1 second ring having a screw threadedend for engaging the internal threads of the lower end of thefirst-named ring, and straining mediums secured to said ringsintermediate their ends.

In testimony whereof I aflix my signature 1n presence of two Witnesses.

DAVID M. BYLANDER.
